Abstract

A constant air volume control method for an air supply device driven by multiple motors. The air supply device comprises at least two BLDC motors which respectively drive different fans and are located in one air duct, wherein each BLDC motor is made into a closed-loop speed control motor; a constant air volume control function is stored in a constant air volume data processor; the constant air volume data processor sends an identical speed signal instruction to the BLDC motors, so that the rotational speeds of the BLDC motors during operation are the same as or equal to each other; each BLDC motor feeds back a motor operating parameter C to the constant air volume data processor, and the constant air volume data processor calculates, according to the motor operating parameter C fed back by each BLDC motor, a motor speed n for keeping the air volume constant and then sends the same speed signal instruction to the BLDC motors. The control method features a simple design and easy implementation, and can implement constant air volume control.
